Having clause is used to filter the group.
Difference between WHERE and HAVING
Where:
WHERE is used to filter rows before grouping.
WHERE clause cannot contain aggregate function likeCOUNT(),SUM(),MAX(),MIN(),AVG().
Having:
HAVING is used to filter records after grouping.
HAVING clause may contain aggregate functions.
WAQ to display the designation and minimum salary in each designation but the minimum salary should be greater
than 2500.
Solution: select designation,min(salary)from empdetails group by designation having min(salary)>2500;
WAQ to display the item code and total unit price for each item code only if the total unit price is greater then
300 from the retail stock table.
Solution:
select itemcode,sum(unitprice)

having sum(unitprice)>300;


Designing an Intuitive Navigation
Gerry McGovern, CEO, Customer Carewords
Navigation
a link is a promise is a commitment, One of the rules of great navigation is not to break a promise. Make a commitment on the link and deliver
Momentum. Navigation should move you forward. Help people move forward not try to go back or confuse the user. People know what they want. Help the user get there with the least confusion.
We have to trust the user intent, and help them continue with their journey. You can still include a way back but should not be so prominent on the page.
Unity is another principal for good navigation design. The more you add in different placecs you confuse people
Icon are a horrible form of navigation, if you are going to use them in navigation put words to describe, icons can mean very different things to people Words are still the primary build block to navigation design. Icons that have labels have a 88% success rate for people to click or choose
Hidden navigation is terrible, when visible navigation increases usage if you take a way the ability to take decisions people stop making decisions. Never hide the navigation
There are exceptions when the hamburger menu can be a good strategy, that is when there is another super task which is the main purpose (like a google map) when you can begin your journey without the navigation. If you have an overwhelming task you can start with that purpose and hide the navigation
Twins: ways on to how to look at a problem. OBJECT-SUBJECT You need to design for both journeys
When a user reaches their desitination remove all the extra information so the user can focus on the task
If your customers are looking at the navigation more the worse experience, the faster they use it to get to a point the better the navigation. Prioritze and give first what users need, so they move at faster pace and reduce frustration.
Magnetism A great link says an action. If a group of links name has a counterpart like Quick links (slow links ? ) then the title is a bad group of links
Method to design a better navigation
Identify what matters the most to your users, and then group those tasks
15 people for usability is the best number for sample to get reliable patterns. Have these 15 people sort the tasks and put them in groups, but do not make them to name them.
Based on data on the most used items determines what goes on the top. Use these as hypothesis and then test them.Tree testing you need to make at least 3 rounds to confirm and learn from the process. At the second round adjust the problems found in round one and confirm
Design principles
- Momentum: Keeo people moving forward
- Unity : Make navigation as unified as possible
- Twins: Design for the jurneys customers are on
- Minimalism: have navigation take up as little space as is practical
- Clarity: Navigation must immediately communicate what it is and what it is not
- Fidelity: A link is a promise. Navigation should keep its promises
- Magnetism: Maximize clean magnetism. Minimize dirty magnetism

KEEP ON YOUR MEMORIES
only SMILE (:
Love does not consist in gazing at each other but in looking together in the same direction.
You can close your eyes to things you don’t want to see, but you can’t close your heart to things you don’t want to feel.
You know when you love someone when you want them to be happy even if their happiness means that you’re not part of it.To love is to risk not being loved in return. To hope is to risk pain. To try is to risk failure, but risk must be taken, because the greatest hazard in life is to risk nothing.A lot of stories happen everyday you could know what had happened yesterday. How can you be sure what will happen tomorrow? Think of something you never say Are you waiting until the day? To say “I LOVE YOU”


| checkTnF {tools} | R Documentation |
Checks the specified R package or code file for occurrences of
T
or F
, and gathers the expression containing these.
This is useful as in R T
and F
are just variables which
are set to the logicals TRUE
and FALSE
by default, but
are not reserved words and hence can be overwritten by the user.
Hence, one should always use TRUE
and FALSE
for the
logicals.
checkTnF(package, dir, file, lib.loc = NULL)
package |
a character string naming an installed package. If given, the installed R code and the examples in the documentation files of the package are checked. R code installed as an image file cannot be checked. |
dir |
a character string specifying the path to a package's root
source directory. This must contain the subdirectory ‘R’ (for
R code), and should also contain ‘man’ (for documentation).
Only used if |
file |
the name of a file containing R code to be checked. Used
if neither |
lib.loc |
a character vector of directory names of R libraries,
or |
An object of class "checkTnF"
which is a list containing, for
each file where occurrences of T
or F
were found, a list
with the expressions containing these occurrences. The names of the
list are the corresponding file names.
There is a print
method for nicely displaying the information
contained in such objects.

DynamoDB Table SSESpecification
The SSESpecification
property is part of the AWS::DynamoDB::Table resource that specifies the settings to enable server-side encryption.
If you do not specify the SSESpecification
property type, Amazon DynamoDB will create an unencrypted table, the same as if you
had specified the SSESpecification
property type with its SSEEnabled
property set to false
. As a best practice, for consistency only specify the SSESpecification
property type (with its SSEEnabled
property set to true
) if you want DynamoDB to create an encrypted table.

Most functionality was retained. However, some of the capability in the truth_manager_class was not incorporated in other classes, namely the ability to follow a track in time. The draw_data_class class can store time info and has the capability to get location at an arbitrary data index (actually at any point between indices as well). The interval_calc_class complements it by calculating the data index given the time series from the draw_data_class. I also added an averaging capability to the draw_data_class (storing average locations in a new array structure).
I transfered all of the functionality of the time_track_class to the draw_data_class. It is still called in roi_manager_class and in cadmodel_manager_class. The roi_manager_class has not been used for a long time and just needs to be rewritten using the new classes. Likewise for the cadmodel_manager_class which was used to move model people along a track for a demo but has not been used in a long time.
The clock management also needs to be transfered from the truth_manager_class to the draw_manager_inv_class.
Joe Mullins wants to add the capability in draw to move units along routes. The speed of each unit would have to be defined. It appears that the way to implement would be to define the start time and the speed and move the unit at that speed until it reached the objective.
A potential problem is that the route would be defined in a very gross way with a smooth route for high-level or large-area presentation. It would be defined much more detailed along roads/valleys etc. at a lower-level or smaller-scale presentation. These may conflict and a unit would really want to move along the more detailed route.
Point Can have name, symbol or time associated Default is to draw symbol if present; if no symbol, draw name if present, if neither draw point itself has altitude-mode Line Can have time associated with each point, a symbol or cadmodel associated with a mover along that line has altitude-mode No name or symbol -- must define a separate point for these Circle Just defined as a line within the code Polygon Just defined as a line within the code

"A Clockwork Orange" has created more diverse reactions in audiences and critics alike than in any other Stanley Kubrick film. Even Kubrick himself was outraged at how the film induced copycat incidents in Great Britain, causing him to ban the film until his death (now it has been re-released since Stanley died in March of 1999). Despite how others feel about the film, in my estimation, this is the greatest film ever made about the nature of violence, and the nature of behavior and moral choice in a clockwork society. It is as relevant and awe-inspiring and as intellectually charged today as any other film since on the subject.
Alex, the punk, the Droog, remains the most ironic, complex, and sympathetic antihero in the history of the cinema. As played by Malcolm McDowell, he is vicious, murderous but also a lover of Beethoven's Ninth Symphony. He also has nude paintings in his bedroom, has masturbatory fantasies to the tune of Beethoven with images from the movies (and himself as Dracula). Alex loves his working-class parents, his boa constrictor, and supposedly goes to school - he seems like a delightful lad you would see in your neighborhood on an "azure sky of deepest summer." There is only one difference - Alex has a knack, a love, for sex and violence. He has a creative imagination but it is fueled by his violent-proned rages - he seems to take delight in killing people.
At the beginning of the film, in stunning close-up, we see Alex at the Korova Milkbar with his fellow Droogs drinking some milk substance that can "sharpen you up and get you ready for a bit of the old ultraviolence." Their nightly activities consist of beating up old winos in dark alleys, attacking people in their homes, driving like madmen on the roads, having sex with women they pick up in record stores, and it is usually all to the tune of Beethoven's lovely Ninth. These Droogs dress in white, have ripped-out eyeball ornamentations on their cuffs, and often wear masks with phallic, Pinocchio noses. Kubrick shows us quite a bit of violence in the first half-hour but he has more up his sleeve as the film continues.
Alex is eventually caught by the police after being betrayed by his fellow Droogs (he is hit in the nose with a milk bottle). Once in prison, he gets wind of a "Ludovico technique" where a prisoner is subjected to a rehabilitative process that results in getting out of prison in no time at all. Alex wants to do good or, as he says, "one act of goodness." The prison chaplain (Godfrey Quigley) tells Alex that the technique has not been tested much and is considered dangerous. As the chaplain explains, "Goodness comes from within - goodness, is chosen. When a man cannot choose, he ceases to be a man." Alex doesn't comprehend such ideas, and decides to take part in the technique at all costs. He gets his chance when the Minister of the Interior (Anthony Sharp), who is looking for criminals to participate in such a technique, chooses Alex whom he considers ruthless, smart, and enterprising.
In what remains surely the most perfectly realized scenes in the film, Alex is strapped to a chair with clamps that keeps his eyelids pried open as he is forced to watch violent film footage - at first, he enjoys it but slowly he becomes nauseous and sickly. Alex is becoming conditioned not just against violence but everything else he enjoys, including Beethoven's Ninth.
So what is Kubrick trying to say? That in a clockwork, mechanized society, we have no rights - we must remain aligned with what is expected? All people who rebel are killers? Alex does not fit into society, he is in fact a rebel, allowing himself to choose violence over nonviolence because that is what makes him tick. Removing his instinctive behavior is not human - it is the result of a dehumanizing society and Alex is as human, direct and joyous as anyone else in the film, including the victims.
Even in today's jaded world of ubiquitous sex and violence, "A Clockwork Orange" is still potent stuff - as disturbing now as it was in 1971. The reason is threefold: we, the audience, can't help but like Alex because he is so charming and ruthless despite his murderous ways. We are also asked to identify with him because we feel he is wronged by society and by the higher-ups who are abusing him and using him for political ambition. And yet Alex is not really cured, we sense he will go back to his violent self.
The violence is both stylized and realistic. It is shown in slow-motion, time-lapse motion, and sometimes "viddied with the red, red vino on tap." When Alex kills his victims, it is shown at a remove, a distance from which we become observers particularly the attack on Alex (Patrick Magee), the Leftist writer, and his wife (Adrienne Corri), to the tune of "Singin' in the Rain." When Alex is attacked by his own droogs (who ironically become policemen) or by other higher-ups, it is realistic and bloody, with none of the enjoyment of "action and performance" that Alex feels when he inflicts pain or kills.
Lastly, the film suggests that Alex cannot be changed by the Ludovico technique - his survival instinct is violence, it is what makes him a person. A moral choice cannot be made, as the prison chaplain says, because you cannot change a person's behavior. A liberal view to be sure but a justifiable view nonetheless.
"A Clockwork Orange" is terrifying, scary, witty, exciting, funny, and exhausting. It is Kubrick's most cinematic odyssey: beautifully shot and choreographed with almost monochromatic tones, and occasionally bursting with some bright, vivid colors of red and black justaxposed with blue and white. Malcolm McDowell gives what may be the seminal performance of any Kubrick film - exuding charm, arrogance and cleverness in the face of a callow, youthful killer. What's disturbing and provoking even today about the film is that Alex wants to retain his moral right to be bad. And we can't help but feel he is right.

Crystal Palace target £20m Celtic striker Odsonne Edouard as competition for Jordan Ayew
Ghana striker Jordan Ayew will have tougher competition at Crystal Palace as they are planning to sign Frenchman Odsonne Edouard took boost the firepower of the English Premier League side.
The 21-year-old, who plays for Scottish side Celtic, has been in blistering from since the start of the season, prompting Palace to seek the signature of the striker.
According to a report the Sun newspaper, Edouard is coach Roy Hodgson first-choice to solving the long-standing striker problem at the South London club where defensive midfielder Luka Milivojevic was the top scorer with 12 goals last season.
Palace have scored 10 goals in 12 matches so far this season with Ayew scoring 4 goals while his fellow strikers Christian Benteke and Wilfred Zaha are still goalless.
With the Frenchman scoring eight times in 11 appearances while contributing five assists, Hodgson is targeting the striker to solve Palace's scoring problems.
But Palace will have to prepare huge amounts of money to sign the former PSG striker for £9million in the summer of 2018 after a year's loan.
Edouard's arrival will give a huge competition to Ayew who has been the most reliable striker for Palace this season.

| lesson 51 Predicting the future |
| Predicting the future is notoriously difficult. |
| Who could have imagined, in the mid 1970s, for example, that by the end of the 20th century, computers would be as common in people's homes as TV sets? |
| In the 1970s, computers were common enough, but only in big business, government departments, and large organizations. |
| These were the so-called mainframe machines. |
| Mainframe computers were very large indeed, often occupying whole air-conditioned rooms, |
| employing full-time technicians and run on specially-written software. |
| Though these large machines still exist, many of their functions have been taken over by small powerful personal computers, commonly known as PCs. |
| In 1975, a primitive machine called the Altair, was launched in the USA. ^ 19 |
| It can properly be described as the first 'home computer' and it pointed the way to the future. |
| This was followed, at the end of the 1970s, by a machine called an Apple. ^ |
| In the early 1980s, the computer giant, IBM produced the world's first Personal Computer. ^ |
| This ran on an 'operating system' called DOS, produced by a then small company named Microsoft. |
| The IBM Personal Computer was widely copied. ^ I |
| From those humble beginnings, we have seen the development of the user-friendly home computers and multimedia machines which are in common use today. |
| Considering how recent these developments are, it is even more remarkable that as long ago as the 1960s, an Englishman, Leon Bagrit, |
| was able to predict some of the uses of computers which we know today. |
| Bagrit dismissed the idea that computers would learn to 'think' for themselves and would 'rule the world', |
| which people liked to believe in those days. |
| Bagrit foresaw a time when computers would be small enough to hold in the hand, |
| when they would be capable of providing information about traffic jams and suggesting alternative routes, |
| when they would be used in hospitals to help doctors to diagnose illnesses, |
| when they would relieve office workers and accountants of dull, repetitive clerical work. |
| All these computer uses have become commonplace. |
| Of course, Leon Bagrit could not possibly have foreseen the development of the Internet, |
| the worldwide system that enables us to communicate instantly with anyone in any part of the world by using computers linked to telephone networks. |
| Nor could he have foreseen how we could use the Internet to obtain information on every known subject, |
| so we can read it on a screen in our homes and even print it as well if we want to. |
| Computers have become smaller and smaller, more and more powerful and cheaper and cheaper. |
| This is what makes Leon Bagrit's predictions particularly remarkable. |
| If he, or someone like him, were alive today, he might be able to tell us what to expect in the next fifty years. |

Setting up Rails Apps with Passenger and Apache in Ubuntu, Ruby, Rails, Apache
Deploy Rails Apps with Passenger and Apache - Ubuntu
Difficulty: 2
Time: 30 minutes
This article explains how to deploy a Rails application with Passenger and Apache in Ubuntu.
The Passenger commands consume a lot of memory. You need at least 1 GB of RAM in a virtual server to run them. Also, it's assumed that you have sudo
privileges to access the virtual server.
Prerequisites
Because the tasks in this article include development library installation and ad hoc compilation on the machine, they are not recommended for a production environment.
Install Apache
-
Update the system, and install Apache.
sudo apt-get -y update
sudo apt-get install apache2
sudo apt-get -y install curl curl-dev apache2-dev mod_ssl
Install Rails and Passenger
- Install Passenger.
sudo apt-get install gem
sudo gem install rails passenger
- Install the Passenger package for Apache.
sudo rvmsudo passenger-install-apache2-module
This installation takes a while.
- Create a new

Or
sudo service apache2 restart
Configure a test Rails application
- Install the SQLite development package to store data in the database.
sudo yum install sqlite-devel
- Go to Apache's web root folder.
cd /var/www/html
- Create a Rails application, and go to the application directory.
rails new Your_application
cd Your_application
- By default, Ubuntu doesn't have JavaScript execution environment installed. So to manually install it, open
Gemfile
in your favourite editor.
sudo vim Gemfile
- Add the following line at the end of the file:
gem 'therubyracer'
- Save and exit.
wq!
- Install the dependencies of

rake db:migrate
Connect the Apache server to the Rails application
- Open the Apache configuration file.
sudo vim /etc/apache2/sites-available/
- In the file, uncomment the following line:
NameVirtualHost *:80
- At the end of this file, add following block of code:
<VirtualHost *:80>
ServerName www.mydomain.com //your server name
DocumentRoot /var/www/html/Your_application/public //your rail application path
<Directory /var/www/html/Your_application/public>
AllowOverride all
Options -MultiViews
</Directory>
</VirtualHost>
- Save and exit.
wq!
- Restart the Apache server.

200 jobs to be created at new vaccine facility in Dundalk over next five years
by Stephen McNeiceA Chinese pharmaceutical company is due to build a new vaccine production facility in Dundalk, creating 200 new jobs over the next five years.
It will be built on WuXi Biologics’ campus in the Co Louth town, with the firm and its vaccine subsidiary hoping to employ a total of 600 people by 2024.
The new facility - which will primarily focus on human vaccine, including for cancer - is expected to cost around €217 million.
Business Minister Heather Humphreys welcomed the news.
She said: "I am delighted to announce 200 highly-skilled jobs in WuXi Vaccines, which is in addition to the 400 roles announced last year by WuXi Biologics for Dundalk.
"Without a doubt, this is a great win for the North-East and a huge vote of confidence in the local workforce."
Dr Chris Chen, chairman of WuXi Vaccines, added: "Due to process complexity, extensive analytic testing and rigorous regulatory standards, vaccines are difficult to manufacture, and process and quality control are extremely critical for the quality of the product.
"This new project to exclusively manufacture a vaccine for the global market is among the first of its kind in the industry and is a further testimony to the technical strengths and premier quality which WuXi Biologics will bring to Dundalk."
The €325 million WuXi campus in Dundalk was first announced in April 2018, with the company saying construction of this facility is "now well underway".

Text description provided by the architects. The Community Centre is located in Conghua District, Guangzhou, Guangdong Province. After the project officially put into use, it will carry the daily leisure activities of nearby residents such as reading, gathering and so on. For this project Shanghai based architecture studio TEAM_BLDG works on both architecture and interior and gets inspired from the local architectural culture. A building deeply bonded with the territory which refers to the form and concept of the traditional local housing typology named Wei Long Wu (Hakka Dragon House).
“Wei Long Wu” (Round Dragon Housing), also named “Long Wu”, is a variation of Hakka architecture, mostly spread around Guangdong Province and is a common form of traditional clan housing. Wei Long Wu uses rammed earth as the outer wall to enclose inner housing which forms multiple concentric semi-circular structures, which have distinct functional zoning. In this project, the design adopts a contemporary composition to break the traditional Hakka architecture's layout. The geometric space is transformed from multiple concentric semicircles into similar triangles. The frames repetition, the plane and the overall scheme emphasizes the depth of field. The resulting configuration creates a visual sensation of layers while maintaining an open space.
Architects attempted to create an architectural form integrating both traditional culture and modern values by employing contemporary theories, structures, materials and therefore the traditional Hakka architecture turning from reclusion to openness.
As Hakka buildings are located in the nature, this double-story building has a close relationship to the surrounding environment: the silhouette of the triangular roof overshadows the ground like a mountain while the metal columns supporting the triangular roof connect with the outdoor trees like a forest. Waterscape around the site smoothens the strict geometries. Large areas of glazing and surrounding green space redefines the relationship between the building and the environment. Elegant roofs, clusters of poles, full height curtain walls: a poem of mountains, trees and water.
A generous canopy welcomes the visitors into the space, a 10m double height featuring suspended wooden boxes. The curtain wall guarantees the same transparent visual experience at all angles. Spaces with different functions are sophisticatedly arranged to be separated while keeping overall integrity: the sunken resting area, the wooden screen hanging from the ceiling, the meeting spaces in between stairs and bookshelves, the private VIP lounge on the second floor.
The sunken resting area is surrounded by water creating an analogy of the patio in Hakka architecture which collects and drains rainwater. The water not only reflects the variations of light and shadow, it also brings greenery into the space and builds up a harmonic environment integrating human and nature.
The main meeting area creates a stable and open atmosphere by emphasizing depth and transparency of the space. Adjacent the lounge is located the coffee bar which is connected to the giant wooden bookcase descending from the upper floor where a more private reading area is located.
A spiral stair is finely designed in the rigid space. The staircase does not require columns thanks to the precise calculation of the steel structure. Visitors have access to the VIP lounge and the offices via this spiral staircase and enjoy the picturesque natural scenes framed by the windows.
To adapt to the local climate, suspended wooden screen in the double height space on the south side are designed to create shading while also contributing to zoning. Meeting spaces, bookshelves and the coffee bar are located here. This vertical waving screen enriches the static and quiet mood echoing the exterior poles while also forming a volume in relation to the functional areas on the second floor.
By approaching the design from both architectural and interior aspects, the integrity of the building is elegantly achieved. The traditional Hakka values are vividly embodied in a contemporary form. The delicate and delightful spaces continue to create unique experiences for visitors. The whole space experience is a continuum, the traditional Hakka village relives in a contemporary spirit with no boundaries.


This library is a Common Lisp wrapper around the DNS-SD C API.

Code is also available on GitHub: https://github.com/tuscland/lw-dns-sd
DNS-SD has no dependencies. Once downloaded, extract the files from the zip archive and load the file defsystem.lisp in LispWorks:
CL-USER 1 > (cd "~/lisp/dns-sd") #P"/Users/camille/lisp/dns-sd/" CL-USER 2 > (load "defsystem") ; Loading text file /Users/camille/lisp/plombier/dns-sd/defsystem.lisp ;; Looking at system "DNS-SD" ;; Looking at system "DNS-SD-TESTS" #P"/Users/camille/lisp/dns-sd/defsystem.lisp"
You can then compile the system:
CL-USER 3 > (compile-system :dns-sd :load t) ;; compilation output... (:DNS-SD)This can also be done using the "Compile System" editor command.
To run the test suite, load the DNS-SD-TESTS system and call

DNS-SD for LispWorks been tested under the following setups:
On Mac OS X, the library has been tested on versions from 10.5.8 to 10.8.2, on machines with Intel processors, 32 and 64 bits executables. On Windows, the library has been tested under Windows 8 with a 32 bits executable.
At this time, there is one example, "examples/browse.lisp". Unlike the file "tests/test.lisp" which also represents a good source of sample code, this example demonstrates how asynchronous callbacks are setup in a GUI application.

Functions in this section are similar to their respective counterparts in the DNS-SD C API.
register
port
type
&key
interface-index
name
domain
host
txt-record
no-auto-rename
callback
➔ operation
Schedules a service registration operation. The service is registered for as long as the operation has not been cancelled.
Signals a
dns-sd-error
if an error immediately occurs.port specifies the port on which the service accepts connections. Pass 0 for a "placeholder" service (i.e. a service that will not be discovered by browsing, but will cause a name conflict if another client tries to register that same name). Most clients will not use placeholder services.
type is the service type followed by the protocol, separated by a dot (e.g. "_ftp._tcp"). The service type must be an underscore, followed by 1-15 characters, which may be letters, digits, or hyphens. The transport protocol must be "_tcp" or "_udp".
If not nil, interface-index specifies the interface on which to look for domains. (the index for a given interface is determined via the if-name-to-index family of calls.) Most applications will pass nil to register on all interfaces.
name, if non nil, specifies the service name to be registered. Most applications will not specify a name, in which case the computer name is used (this name is communicated to the client via the callback).
domain, if non nil, specifies the domain on which to advertise the service. Most applications will not specify a domain, instead automatically registering in the default domain(s).
host, if non nil, specifies the SRV target host name. Most applications will not specify a host, instead automatically using the machine's default host name(s). Note that specifying a non nil host does NOT create an address record for that host - the application is responsible for ensuring that the appropriate address record exists, or creating it via register-record.
txt-record specifies the txt-record associated with the service. It must be an association-list of key/value strings pairs.
no-auto-rename specifies renaming behavior on name conflict when registering non-shared records. By default, name conflicts are automatically handled by renaming the service. no-auto-rename overrides this behavior — with this flag set, name conflicts will result in a callback. The no-auto-rename option is only valid if a name is explicitly specified when registering the service (i.e. the default name, nil, is not used.)
When callback is specified, the operation is run asynchronously and results are delivered through the callback. callback must be a function of two arguments: operation and result where operation is the object returned by this function, and result is either a result, or an error if an error occurred in the dispatch process.
For register, the result object contains the following named values:
:PRESENCE
—:ADD
is used when the service has been successfully published, and:REMOVE
when the service is about to be renamed in case of conflict resolution.:NAME
— the service name registered (if the application did not specify a name in register, this indicates what name was automatically chosen).:TYPE
— the type of service registered, as it was passed to the callout.:DOMAIN
— the domain on which the service was registered (if the application did not specify a domain in register, this indicates the default domain on which the service was registered).See DNSServiceRegister.
enumerate-domains
&key
interface-index
domains
callback
➔ operation
Schedules a domains enumeration operation.
Signals a
dns-sd-error
if an error immediately occurs.interface-index if not nil specifies the interface on which to look for domains. (the index for a given interface is determined via the if-name-to-index family of calls.) Most applications will pass nil to enumerate domains on all interfaces.
domains specifies the enumerated domains. The value can be
:BROWSE-DOMAINS
(the default value) or:REGISTRATION-DOMAINS
.When callback is specified, the operation is run asynchronously and results are delivered through the callback. callback must be a function of two arguments: operation and result where operation is the object returned by this function, and result is either a result, or an error if an error occurred in the dispatch process.
For enumerate-domains, the result object contains the following named values:
:PRESENCE
—:ADD
or:REMOVE
depending on domains being found or lost.:DEFAULTP
— is t if the domain is the default domain.:INTERFACE-INDEX
— the interface on which the domain exists. (The index for a given interface is determined via the if-name-to-index family of calls.):DOMAIN
— the name of the domain.
browse
type
&key
interface-index
domain
callback
➔ operation
Schedules a browse operation.
Signals a
dns-sd-error
if an error immediately occurs.type is the service type being browsed for followed by the protocol, separated by a dot (e.g. "_ftp._tcp"). The transport protocol must be "_tcp" or "_udp". A client may optionally specify a single subtype to perform filtered browsing: e.g. browsing for "_primarytype._tcp,_subtype" will discover only those instances of "_primarytype._tcp" that were registered specifying "_subtype" in their list of registered subtypes.
If not nil, interface-index specifies the interface on which to look for domains. (the index for a given interface is determined via the if-name-to-index family of calls.) Most applications will pass nil to browse on all interfaces.
domain, if non nil, specifies the domain on which to advertise the service. Most applications will not specify a domain, instead automatically registering in the default domain(s).
When callback is specified, the operation is run asynchronously and results are delivered through the callback. callback must be a function of two arguments: operation and result where operation is the object returned by this function, and result is either a result, or an error if an error occurred in the dispatch process.
For browse, the result object contains the following named values:
:PRESENCE
—:ADD
or:REMOVE
depending on services being found or lost.:INTERFACE-INDEX
— the interface on which the service is advertised. This index should be passed to resolve when resolving the service.:NAME
— the discovered service name. This name should be displayed to the user, and stored for subsequent use in the resolve call.:TYPE
— the service type, which is usually (but not always) the same as was passed to browse. One case where the discovered service type may not be the same as the requested service type is when using subtypes: The client may want to browse for only those ftp servers that allow anonymous connections. The client will pass the string "_ftp._tcp,_anon" to browse, but the type of the service that's discovered is simply "_ftp._tcp". The regtype for each discovered service instance should be stored along with the name, so that it can be passed to resolve when the service is later resolved.:DOMAIN
— the domain of the discovered service instance. This may or may not be the same as the domain that was passed to browse. The domain for each discovered service instance should be stored along with the name, so that it can be passed to resolve when the service is later resolved.See DNSServiceBrowse.
resolve
name
type
domain
&key
interface-index
broadcasting
callback
➔ operation
Schedules a resolve operation.
Signals a
dns-sd-error
if an error immediately occurs.name, type and domain must be specified as the result values obtained from a browse operation.
interface-index specifies the interface on which to resolve a service. If this resolve call is as a result of a currently active browse operation, then the interface-index should be the index reported in the result. If this resolve call is using information previously saved (e.g. in a preference file) for later use, then use a nil interface-index, because the desired service may now be reachable via a different physical interface.
When broadcasting is
:FORCE-MULTICAST
the query is performed with a link-local mDNS query, even if the name is an apparently non-local name (i.e. a name not ending in ".local.").When callback is specified, the operation is run asynchronously and results are delivered through the callback. callback must be a function of two arguments: operation and result where operation is the object returned by this function, and result is either a result, or an error if an error occurred in the dispatch process.
For resolve, the result object contains the following named values:
:INTERFACE-INDEX
— the interface on which the service was resolved.:FULL-NAME
— the full service domain name, in the form<servicename>.<protocol>.<domain>
.:HOSTNAME
— the target hostname of the machine providing the service.:PORT
— the port on which connections are accepted for this service.:TXT-RECORD
— the service's primary txt record, as an association-list of strings.See DNSServiceResolve.
get-addr-info
hostname
&key
interface-index
protocols
broadcasting
callback
➔ operation
Schedules an IP address resolution operation.
Signals a
dns-sd-error
if an error immediately occurs.hostname, specifies the fully qualified domain name of the host to be queried for, that should be the resulting value of a resolve operation.
interface-index specifies the interface on which to issue the query. Passing nil causes the query to be sent on all active interfaces via Multicast or the primary interface via Unicast.
protocols must be nil or a list of keywords containing
:IPV4
to look up for IPv4 addresses,:IPV6
to look up for IPv6 addresses, or both keywords. If neither flag is set, the system will apply an intelligent heuristic, which is (currently) that it will attempt to look up both, except: if hostname is a wide-area unicast DNS hostname (i.e. not a ".local." name) but this host has no routable IPv6 address, then the call will not try to look up IPv6 addresses for hostname, since any addresses it found would be unlikely to be of any use anyway. Similarly, if this host has no routable IPv4 address, the call will not try to look up IPv4 addresses for hostname.broadcasting can be
:FORCE-MULTICAST
or:LONG-LIVED-QUERY
. Use:LONG-LIVED-QUERY
to create a "long-lived" unicast query to a unicast DNS server that implements the protocol; this option has no effect on link-local multicast queries.When callback is specified, the operation is run asynchronously and results are delivered through the callback. callback must be a function of two arguments: operation and result where operation is the object returned by this function, and result is either a result, or an error if an error occurred in the dispatch process.
For get-addr-info, the result object contains the following named values:
:PRESENCE
—:ADD
on successful address resolutions.:INTERFACE-INDEX
— the interface to which the answers pertain.:HOSTNAME
— the fully qualified domain name of the host to be queried for.:ADDRESS
— IPv4 or IPv6 address.:TTL
— if the client wishes to cache the result for performance reasons, the TTL indicates how long the client may legitimately hold onto this result, in seconds. After the TTL expires, the client should consider the result no longer valid, and if it requires this data again, it should be re-fetched with a new query.   The NAT port mapping exists for as long as the operation in pending (i.e. not cancelled).
Signals a
dns-sd-error
if an error immediately occurs.internal-port specifies the port number on the local machine which is listening for packets.
interface-index specifies the interface on which to create port mappings in a NAT gateway. Passing nil causes the port mapping request to be sent on the primary interface.
external-port specifies the requested external port in the NAT gateway that you would like to map to the internal port. Pass 0 if you don't care which external port is chosen for you.
protocols must be nil or a list of keywords containing
:UDP
,:TCP
, or both. The local listening port number must also be specified in the internal-port parameter. To just discover the NAT gateway's external IP address, pass 0 for internal-port, and leave the default value nil for protocols, external-port and ttl.ttl specifies the requested renewal period of the NAT port mapping, in seconds. Most clients should use the default value.
When callback is specified, the operation is run asynchronously and results are delivered through the callback. callback must be a function of two arguments: operation and result where operation is the object returned by this function, and result is either a result, or an error if an error occurred in the dispatch process.
For nat-port-mapping-create, the result object contains the following named values:
:INTERFACE-INDEX
— the interface through which the NAT gateway is reached.:EXTERNAL-ADDRESS
— IPv4 address string.:PROTOCOLS
— the list of protocols used ::UDP
,:TCP
or both.:INTERNAL-PORT
— the port on the local machine that was mapped.:EXTERNAL-PORT
— the actual external port in the NAT gateway that was mapped. This is likely to be different than the requested external port.:TTL
— the lifetime of the NAT port mapping created on the gateway. This controls how quickly stale mappings will be garbage-collected if the client machine crashes, suffers a power failure, is disconnected from the network, or suffers some other unfortunate demise which causes it to vanish without explicitly removing its NAT port mapping. It's possible that the ttl value will differ from the requested ttl value.
query-record
full-name
rrtype
&key
interface-index
rrclass
broadcasting
callback
➔ record-ref
Schedules a resource record query.
Signals a
dns-sd-error
if an error immediately occurs.full-name is the full domain name of the resource record to be queried for. The function construct-full-name can be used to help format this string.
rrtype is a keyword representing the type of the record. Valid keywords are: :A :NS :MD :MF :CNAME :SOA :MB :MG :MR :NULL :WKS :PTR :HINFO :MINFO :MX :TXT :RP :AFSDB :X25 :ISDN :RT :NSAP :NSAP_PTR :SIG :KEY :PX :GPOS :AAAA :LOC :NXT :EID :NIMLOC :SRV :ATMA :NAPTR :KX :CERT :A6 :DNAME :SINK :OPT :APL :DS :SSHFP :IPSECKEY :RRSIG :NSEC :DNSKEY :DHCID :NSEC3 :NSEC3PARAM :HIP :SPF :UINFO :UID :GID :UNSPEC :TKEY :TSIG :IXFR :AXFR :MAILB :MAILA :ANY.
interface-index, if non nil, specifies the interface on which to issue the query (the index for a given interface is determined via the if-name-to-index family of calls.) Passing nil causes the name to be queried for on all interfaces.
rrclass has only one value at this moment, :IN.
broadcasting can be
:FORCE-MULTICAST
or:LONG-LIVED-QUERY
. Use:LONG-LIVED-QUERY
to create a "long-lived" unicast query to a unicast DNS server that implements the protocol; this option has no effect on link-local multicast queries.When callback is specified, the operation is run asynchronously and results are delivered through the callback. callback must be a function of two arguments: operation and result where operation is the object returned by this function, and result is either a result, or an error if an error occurred in the dispatch process.
For query-record, the result object contains the following named values:
:PRESENCE
—:ADD
on successful query replies,:REMOVE
for PTR records with a 0 ttl, i.e. "Remove" events.:INTERFACE-INDEX
— the interface on which the query was resolved (the index for a given interface is determined via the if-name-to-index family of calls).:FULL-NAME
— the resource record's full domain name.:RRTYPE
— the resource record's type. (e.g.:PTR
,:SRV
, etc.):RRCLASS
— the class of the resource record. (usually:IN
.):RDATA
— the raw rdata of the resource record, as an array of(unsigned byte)
elements.:TTL
— if the client wishes to cache the result for performance reasons, the TTL indicates how long the client may legitimately hold onto this result, in seconds. After the TTL expires, the client should consider the result no longer valid, and if it requires this data again, it should be re-fetched with a new query.  Clients that leave the asynchronous operation running can safely assume that the data remains valid until they get another callback telling them otherwise.
add-record
operation
rrtype
rdata
&key
ttl
➔ record-ref
Adds a records to a registered service. The name of the record will be the same as the registered service's name. The record can later be updated or deregistered by passing the record-ref returned by this function to update-record or remove-record.
Signals a
dns-sd-error
if an error immediately occurs.operation must be a running operation returned by a call to register.
rrtype is a keyword representing the type of the record. Valid keywords are: :A :NS :MD :MF :CNAME :SOA :MB :MG :MR :NULL :WKS :PTR :HINFO :MINFO :MX :TXT :RP :AFSDB :X25 :ISDN :RT :NSAP :NSAP_PTR :SIG :KEY :PX :GPOS :AAAA :LOC :NXT :EID :NIMLOC :SRV :ATMA :NAPTR :KX :CERT :A6 :DNAME :SINK :OPT :APL :DS :SSHFP :IPSECKEY :RRSIG :NSEC :DNSKEY :DHCID :NSEC3 :NSEC3PARAM :HIP :SPF :UINFO :UID :GID :UNSPEC :TKEY :TSIG :IXFR :AXFR :MAILB :MAILA :ANY.
rdata is the raw rdata to be contained in the added resource record. It must be an array of (unsigned byte 8) elements. The contents of the data depends on the record type.
ttl specifies the time to live of the resource record, in seconds. Most clients should pass 0 to indicate that the system should select a sensible default value.
See DNSServiceAddRecord.
update-record
operation
record-ref
rdata
&key
ttl
Updates a registered resource record. The record must either be:
- The primary TXT record of a service registered via register,
- A record added to a registered service via add-record,
- An individual record registered by register-record.
Signals a
dns-sd-error
if an error immediately occurs.operation must be a running operation returned by a call to register, or create-connection.
record-ref may be nil to update the primary TXT record, or the value returned by a call to add-record, or register-record.
rdata is the new raw rdata contained in the updated resource record. It must be an array of (unsigned byte 8) elements. The contents of the data depends on the record type.
ttl specifies the time to live of the resource record, in seconds. Most clients should pass 0 to indicate that the system should select a sensible default value.
remove-record
operation
record-ref
Removes a record previously added to a service record set via add-record or register-record.
Signals a
dns-sd-error
if an error immediately occurs.operation must be a running operation returned by a call to register (if the record being removed was registered via add-record), or create-connection (if the record being removed was registered via register-record).
record-ref must be the value returned by a call to add-record, or register-record.
create-connection
&key
callback
➔ operation
Creates a connection to the daemon allowing efficient registration of multiple individual records.
Signals a
dns-sd-error
if an error immediately occurs.When callback is specified, the operation is run asynchronously and results are delivered through the callback. callback must be a function of two arguments: operation and result where operation is the object returned by this function, and result is either a result, or an error if an error occurred in the dispatch process.
See register-record for more information on the results delivered through the callback used with this function.
register-record
operation
full-name
rrtype
rdata
&key
interface-index
rrclass
identity
ttl
➔ record-ref
Registers resource records.
Signals a
dns-sd-error
if an error immediately occurs.operation must be a running operation returned by a call to create-connection.
full-name specifies the full domain name of the resource record. The function construct-full-name can be used to format this string.
rrtype is a keyword representing the type of the record. Valid keywords are: :A :NS :MD :MF :CNAME :SOA :MB :MG :MR :NULL :WKS :PTR :HINFO :MINFO :MX :TXT :RP :AFSDB :X25 :ISDN :RT :NSAP :NSAP_PTR :SIG :KEY :PX :GPOS :AAAA :LOC :NXT :EID :NIMLOC :SRV :ATMA :NAPTR :KX :CERT :A6 :DNAME :SINK :OPT :APL :DS :SSHFP :IPSECKEY :RRSIG :NSEC :DNSKEY :DHCID :NSEC3 :NSEC3PARAM :HIP :SPF :UINFO :UID :GID :UNSPEC :TKEY :TSIG :IXFR :AXFR :MAILB :MAILA :ANY.
rdata is the raw rdata to be contained in the registered resource record. It must be an array of (unsigned byte 8) elements. The contents of the data depends on the record type.
interface-index if non nil, specifies the interface on which to register the record (the index for a given interface is determined via the if-name-to-index family of calls.) Passing nil causes the record to be registered on all interfaces.
rrclass is the class of the resource record, currently supported value is :IN
identity when non nil, can have the keyword value :SHARED or :UNIQUE. :SHARED indicates that there may be multiple records with this name on the network (e.g. PTR records). :UNIQUE indicates that the record's name is to be unique on the network (e.g. SRV records).
ttl specifies the time to live of the resource record, in seconds. Most clients should pass 0 to indicate that the system should select a sensible default value.
Callback replies are made on the callback specified when the operation was created, using create-connection. For register-record, the result object contains the following named values:
:RECORD-REF
— the record-ref object that can be used in other functions operating on records (e.g. update-record.
reconfirm-record
full-name
rrtype
rdata
interface-index
&key
rrclass
force
Instructs the daemon to verify the validity of a resource record that appears to be out of date (e.g. because TCP connection to a service's target failed.) Causes the record to be flushed from the daemon's cache (as well as all other daemons' caches on the network) if the record is determined to be invalid. Use this routine conservatively. Reconfirming a record necessarily consumes network bandwidth, so this should not be done indiscriminately.
Signals a
dns-sd-error
if an error immediately occurs.full-name specifies the full domain name of the resource record. The function construct-full-name can be used to format this string.
rrtype is a keyword representing the type of the record. Valid keywords are: :A :NS :MD :MF :CNAME :SOA :MB :MG :MR :NULL :WKS :PTR :HINFO :MINFO :MX :TXT :RP :AFSDB :X25 :ISDN :RT :NSAP :NSAP_PTR :SIG :KEY :PX :GPOS :AAAA :LOC :NXT :EID :NIMLOC :SRV :ATMA :NAPTR :KX :CERT :A6 :DNAME :SINK :OPT :APL :DS :SSHFP :IPSECKEY :RRSIG :NSEC :DNSKEY :DHCID :NSEC3 :NSEC3PARAM :HIP :SPF :UINFO :UID :GID :UNSPEC :TKEY :TSIG :IXFR :AXFR :MAILB :MAILA :ANY.
rdata is the raw rdata of the resource record. It must be an array of (unsigned byte 8) elements. The contents of the data depends on the record type.
interface-index specifies the interface of the record in question. The caller must specify the interface. This API (by design) causes increased network traffic, so it requires the caller to be precise about which record should be reconfirmed. It is not possible to pass +interface-index-any+ for the interface index to perform a "wildcard" reconfirmation, where *all* matching records are reconfirmed.
rrclass is the class of the resource record, currently supported value is :IN
force pass t to force immediate deletion of record, instead of after some number of reconfirmation queries have gone unanswered.
wait-for-result
operation
&key
timeout
➔ result
Use this function to get the results of a running operation in a synchronous fashion. Returns a result if the call succeed in less that timeout seconds. If the result is a result-error that occurred within the dispatch loop, a call to wait-for-result will raise the error.
operation must be an operation returned by the DNS-SD Operations family of calls.
timeout is the time in seconds at which the function will raise a timeout-error. If nil is passed, the timeout is infinite (there is no timeout). The default value is *default-timeout*.
*default-timeout*
Default value (60 seconds) for functions that requires a timeout keyword argument. nil means infinite wait.
cancel
operation
&key
callback
timeout
Cancel a running operation.
operation must be a running operation.
With callback being nil, the call is synchronous, and operation is canceled after the call has returned. Otherwise, callback is a function of no argument called from the dispatch process when the operation is canceled, in which case the argument timeout is ignored.
timeout specifies the time in seconds after which the function signals a timeout-error. If nil, the wait is infinite. Default value is *cancel-timeout*.
result-more-coming-p
result
➔ boolean
Indicates that at least one more result is queued and will be delivered following immediately after this one. When the result-more-coming-p is t, applications should not immediately update their UI, because this can result in a great deal of ugly flickering on the screen, and can waste a great deal of CPU time repeatedly updating the screen with content that is then immediately erased, over and over. Applications should wait until result-more-coming-p is nil, and then update their UI when no more changes are imminent.
result-values
result
➔ property-list
Throws an error when used with an error-result.
Returns the property-list of keyword / value pairs representing the values of a previously ran operation.
result-value
result
name
➔ value
Throws an error when the result has no such named value.
Returns the named value contained in result where name is a keyword. Valid keywords depend on the result of the operation.
start-dispatch
Start the dispatch process. There is generally no need to call this function as it is automatically called by functions of the Main API when the dispatch process is not running.
stop-dispatch
Synchronously stop the dispatch process and cancels every pending operation.
if-name-index
➔ alist
Returns an association-list of (interface-index . interface-name) pairs.
result-error
(dns-sd-error)
Errors occuring in operations callback are of this type. Use the reader function result-error-code to get the original error code.
timeout-error
(dns-sd-error)
Functions accepting a
:TIMEOUT
keyword argument will raise an error of this type once the timeout has been reached.
daemon-version
➔ integer
Returns the version of the mDNS daemon running on the local machine.
build-txt-record
alist
➔ array
Build a TXT record byte array from an association-list of strings key-pairs.
parse-txt-record
array
➔ alist
Parse an array of bytes containing TXT record data, and returns an association-list of strings key-pairs.
construct-full-name
service
type
domain
➔ string

What is dyslexia?
Dyslexia is a language processing problem, a specific difficulty in learning one or more of spelling, writing or reading.
Many dyslexics experience visual stress and have difficulty in distinguishing between printed letters in books and in tracking words across the page when reading.
It should be diagnosed by a professional. Always speak with your child’s school first if you have any concerns.
What is Irlen syndrome?
Some dyslexics also have Irlen syndrome. That means they also have a problem with visual perception.
Glare from white paper is particularly stressful for people with Irlen syndrome so they too may find that cream paper is more comfortable to read from.
It can be diagnosed by qualified screeners and Irlen diagnosticians.
How our libraries can help children with dyslexia and Irlen syndrome
We stock physical books from the dyslexia-specialist publisher, Barrington Stoke. These books are dyslexia-friendly by having the following features:
- Text printed on cream paper with a matt surface to mitigate the effect of glare from white paper.
- Thick paper, since dyslexics experience reading problems when print from overleaf show through on the reading page.
- Specially-created type face designed to minimise visual stress by using slightly longer ascenders and descenders on letters.
- A wider gap between each line of text, clear punctuation and a more defined gap between paragraphs.
Our eBook services allow you to change both page colour and font size to create a bespoke visual experience for your child. Learn more about our e-services.
We also stock physical and online audio books free of charge. Your child may enjoy just listening to the story, or want to read the print version at the same time.
We also stock books for adults about dyslexia and other learning difficulties.
How you can help children with dyslexia and Irlen syndrome
Dyslexic children often have problems with spelling and handwriting. Parent Champions offers very practical tips for adults helping children.
If your child has Irlen syndrome, placing a simple coloured overlay across the page of a book could make it easier for your child to read. Experiment at home using a pack of multi-coloured transparent sheets (bought from any stationers). It could considerably extend the range of books your child can choose from at very small cost.
Tips on choosing books
- If a child is unable to read 5 or more words on a page, then the book is too difficult.
- Choose a book about a topic they are interested in.
- Factual books may be easier for children with reading difficulties. Look for well-illustrated books with short captions.
- Avoid books with cluttered pages.
- Cookery books, craft books and joke books convey a lot of meaning in simple sentences.
- There is a list of dyslexia-friendly books for children of all ages at Lovereading4kids.
